Hyper-hyperlinking

In this item, as well as in many others, too many words have been linked as wikiwords. As the article is about achromatopsia, linking flesh might not be a good idea. To demonstrate the effect, I hyper-hyperlinked this opinion. Please link words that are central or might require explaining in context. Linking all means the writer does not know what is central. 91.152.95.139 (talk) 10:15, 9 May 2008 (UTC)[reply]

Dyschromatopsia, spatial acuity etc.

I have conducted research on cerebral achromatopsia, although, as you'll see, I'm not that sure how to edit Wikipedia. There are a couple of issues with the entry. First, I've been lead to believe that Oliver Sacks' case Jonathan I might be dyschromatopsic rather than achromatopsic (so he retains colour experience over a restricted range of colours - otherwise how could he have a preference for painting using one particular palette of colours?). Second, I am surprised by the assertion that cerebral achromatopsics always have poor spatial acuity - those I have tested certainly don't (patient MS, for example, can read fine newsprint). I've added (eventually - I struggled with the formatting) references for the ability of cerebral achromatopsics to discriminate wavelength contrast across edges (both refs are mine): Kentridge, R.W.; Heywood, C.A. & Cowey, A. (2004) Chromatic edges, surfaces & constancies in cerebral achromatopsia. Neuropsychologia 42, 821-830. Heywood, C.A. & Kentridge, R.W. (2003) Achromatopsia, color vision & cortex. Neurological Clinics of North America 21, 483-500. — Preceding unsigned comment added by 86.174.126.248 (talk) 20:40, 14 December 2011 (UTC)[reply]

Color Agnosia

Considering Color agnosia redirects to this page, there is a real dearth of information here on it, and no discussion on why it is really different from cerebral achromatopsia. After some minor searching, there seems to be a lot of conflation between the two in the literature. Cerebral Achromatopsia is even listed as a type of agnosia. Can anyone elucidate?
